Description Andreas Peichert

The UCRv samba4/sysvol/sync/host contains a concatenation of all ad-dc in the same domain, which leads to an error in sysvol-sync.sh because such a host does not exist for ssh.

2021-05-10 13:23:30 ERROR [dc1dc2] placing triggerfile with ssh failed with 255. (ssh: connect to host dc1dc2 port 22: No route to host)
2021-05-10 13:23:30 ERROR [dc1dc2] Placing a trigger file failed.

I would expect the UCRv "host" does only point to one system, or have to split the concatenation of many hosts.

To reproduce: Install the samba4 App at all systems at the same time
dc1 master
dc2 backup
pt1 slave → samba4/sysvol/sync/host="dc1dc2"

Uninstall the second samba ad-dc and manually set samba4/sysvol/sync/host="dc1" resolve this for the customer.
